This wide-ranging, heavily illustrated analysis of 20th-century warfare, with contributions from distinguished military historians from the United States, Canada, Britain, Germany, and France, conveys the horror and drama of two world wars, the conflicts and civil wars of the 1920s and 1930s, the Cold War, wars of independence and decolonization, and Middle Eastern wars after 1945. Along with extensive lists of key events and spotlights on technological innovations, from the tank and the nuclear bomb to the submarine and the unmanned aerial drone, the book features 300 photographs—240 in color—and specially commissioned maps and battle reconstructions.
